+title: Create a New Jekyll Post with a Simple Shell Command
+description: If you are lazy like me you need something to automate a new post for Jekyll
+categories: ["Jekyll", "Coding"]
+---
+
+Let's build a shell command to automate the creation of a new post in Jekyll.
+
+This will be a short one.
+
+Jekyll has its quirks, and I always wondered why they don't have a simple command to create a new post. I used to copy/paste the previous one, but you know how things are... If you can automate something boring in a few minutes, just do it.
+
+## Creating the Script
+We first need to create a simple bash script to do the job for us.
+
+So, create a new file. I call mine `newjekyllpost.sh` and add the following parts to it:
+
+```bash
+#!/bin/bash
+filename=`date +%Y-%m-%d-new-post.md`
+
+cat > $filename <<EOF
+---
+layout: post
+title: A title
+description: A description
+categories: ["tag"]
+social_image: add here
+---
+EOF
+```
+
+Let's rubberduck this.
+
+The second line is a variable called `filename`. This will be used for our file name with today's date and the following format:
+```
+YYYY-MM-DD-new-post.md #
+```
+
+The third line will create the file with the contents we like. I chose to add the YAML front matter with the most used content for my posts. If I don't want something, I remove it.
+
+And that's it. Our script is that simple. Let's now try to execute it.
+
+## Making the Script Executable
+
+If you try to run it, you will get an error about permissions. There is one more step, which is to change the file's permissions.
+
+```
+chmod u+x ./newjekyllpost.sh
+```
+
+After that, running `./newjekyllpost.sh` will create a file in the specific folder with our contents.
+
+## Adding an Alias
+
+Let's do one more last thing to make our lives easier.
+
+Right now, we have our script in a specific folder, so we need to write the path each time, which is also boring. Adding an alias for the script will work like magic.
+
+Move the script to any path you want. I keep a `scripts` folder inside my `Users` folder.
+
+Open the profile your shell is using. I'm using ZSH, so I have this line in my `.zshrc` file:
+
+```
+alias njp="~/scripts/newjekyllpost.sh"
+```
+
+Every time I run `njp` in a folder, the script creates a new file. You can choose any alias you want, of course.
+
+Run `source pathoftheprofilefile` to reload the new changes, and we are done.
+
+## Improving the Script
+
+As I was writing this, I though there is one more thing we could do to improve the script. If there are argguments to the script use them to postfix the filename.
+
+So our first part of the script becomes:
+
+```
+if [ $# -gt 0 ]
+then
+  filename=`date +%Y-%m-%d-`
+  filename+=`echo "$@" | sed -e 's/ /-/g'`.md
+else
+  filename=`date +%Y-%m-%d-new-post.md`
+fi
+```
+
+In the "bash" language what that means is:
+
+If I have arguments add the date in the filename. Then join with a space all the arguments as string with `"$@"` and then replace the spaces with `-` which is done by the `sed` part.
+
+If I have no arguments, business as usual.
+
+If we run `njp this is my new post` at 2022-12-30 the file will be create will have the following name:
+
+```
+2022-12-30-this-is-my-new-post.md
+```
+
+Just remember, all of this can be achieved with any language. The logic is the same. I just chose to do it in a bash script because, why not?
